Bug 237793

Application: rekonq (0.4.68)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I have multiple tabs open (around 5) which were restored via the session save feature. I finish reading one, click the close icon on the tab and rekonq crashes. This has happened several times now. Will try and see if I can make it 100% reproducible.

 -- Backtrace:
Application: rekonq (kdeinit4), signal: Segmentation fault
